Water quality assessment in the region of Fez based on the physicochemical and ecotoxicological investigations is presented. The results indicate that sites located close to the most urbanized and industrialized areas are severely impaired. The major water quality problems are: low dissolved oxygen (DO), high turbidity, organic matter and ammonia contents, severe chromium and copper pollution and high acute and chronic toxicity. This results in the loss of the aquatic life which is still flourishing in the Fez River upstream from the Fez Medina. Remote sites downstream show signs of physicochemical recovery. However, even there, bioassays showed significant acute and chronic toxicity. Well water in the region of Fez has moderately poor water quality with nitrate and metal enrichments. Use of water for drinking or for agriculture from the rivers or from some wells without treatment may expose the population to health risk.
本文介绍了基于理化和生态毒理学调查的非斯地区水质评估情况。结果表明，靠近城市化和工业化程度最高地区的地点受到严重损害。主要的水质问题包括：溶解氧（DO）含量低、浊度高、有机物和氨含量高、铬和铜污染严重以及急性和慢性毒性高。这导致了水生生物的死亡，而在非斯麦地那上游的非斯河中，水生生物原本十分繁盛。下游偏远地区显示出理化指标恢复的迹象。然而，即便在那里，生物检测仍显示出显著的急性和慢性毒性。非斯地区的井水水质中等偏差，存在硝酸盐和金属富集现象。未经处理就使用河水或一些井水进行饮用或农业灌溉，可能会使民众面临健康风险。
